Step-by-step explanation:
The circumference of the clock will be 8.6π because its hand is the radius. In 15 minutes the hand moves a quarter of the circumference which is 2.15π or 6.571.
Answer:
Can u show the whole question
Answer:
(since they're similar, set them up as a proportion to find x)
14*14 = 8(x+2) (cross multiply, solve the left side, and distribute the right side)
196 = 8x +16 (subtract 16 from both sides)
180 = 8x (divide both sides by 8)
x= 22.5 (is your answer, or C)
Step-by-step explanation:
Answer: Given radius (R) = 50
Diameter = 2R = 100
Circumference = 2πR
= 100π
= 314.15926535898
Area = πR2
= 2500π
= 7853.9816339745
